Things soured between the two companies after the Facebook acquisition
Twitter is starting to feel the effects of Facebook acquiring Instagram, or the effects of its push to control more of the ecosystem at the detriment of third-party developers. Twitter's big strategy is to have developers create apps that run on Twitter itself, inside the so-called Twitter cards.But it seems Instagram has had enough of it and has cut off Twitter's access for the cards feature resulting in problems for anyone that embedded an Instagram photo on Twitter.
"Users are experiencing issues with viewing Instagram photos on Twitter. Issues include cropped images," Twitter explained.
"This is due to Instagram disabling its Twitter cards integration, and as a result, photos are being displayed using a pre-cards experience. So, when users click on Tweets with an Instagram link, photos appear cropped," it said.
It's unclear whether this is a temporary situation, but it doesn't sound like it. Twitter and Instagram were very close up to the Facebook acquisition, but things changed after that.
The fact that Twitter is working on adding photo filters to its own mobile apps can't have helped things, though Instagram can't seriously consider this a threat.
Instagram has confirmed the move and said it wanted to boost its own web presence. Instagram recently unveiled web profiles for all of its users, a big move for the mobile-only company.
